DETAILED DESCRIPTION

The following describes the exemplary embodiments of the present disclosure with reference to the accompanying drawings, which includes various details of the embodiments of the present disclosure to facilitate understanding, which shall be considered merely exemplary. Therefore, those of ordinary skill in the art should recognize that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of the present disclosure. For clarity and conciseness, descriptions of well-known functions and structures are omitted in the following description.

In the description of embodiments of the disclosure, the term “includes” and its equivalents should be understood as an open “include” (a non-exclusive “include”), that is, “include but not limited to”. The term “based on” should be understood as “based at least in part (at least partially based on)”. The term “an embodiment” or “the embodiment” should be understood as “at least one embodiment”. The terms “first”, “second”, and the like may refer to different or the same objects. Other explicit and implicit definitions may also be included below.

With development of processor technologies, computing speeds of current processors have exceeded read and write efficiency of memories. In a progress of the processor executing instructions, the processor often waits for data to be obtained from the memory. Particularly to AI processors, complexity of computing is not high, but the amount of data to be processed is very large. Therefore, transmission efficiency of data in the memory has become a bottleneck in data processing. This situation becomes more serious when the number of cores inside the processor expands.

When the processor accesses the memory, multiple instructions to access the memory have different execution delays, resulting in operations actually initiated on the memory not achieving expectations. In order to avoid this situation, an instruction that manages memory access (such as an mfence instruction) is usually inserted between any two instructions that access the memory. For example, the mfence instructions may be used to separate respective instructions, which causes the next memory access instruction to be read when execution of the previous instruction completes. However, in this way, execution time of the processor is increased and efficiency of the processor is reduced.

In order to solve the above problems, one solution is to restrict the mfence instruction. When the next instruction is not a memory access instruction, the instruction is read normally, and when the next instruction is the memory access instruction, the processor will be blocked. However, although non-memory access instructions may be executed in this way, execution of the next memory access instruction still requires to wait until the execution of the previous memory access instruction completes, so efficiency of data processing between the processor and the memory is still low.

In order to at least solve the above-mentioned problems, an improved scheme for executing instructions is provided according to the embodiments of the present disclosure. A computing device obtains a first memory access instruction for execution, in which the first memory access instruction includes a first address range of a memory to be accessed. The computing device, in response to detecting a predetermined instruction for monitoring an accessed address range of the memory, executes the predetermined instruction to obtain a remaining address range not accessed by the first memory access instruction in the first address range. The computing device compares the remaining address range with a second address range included in a second memory access instruction to be executed. The computing device suspends execution of the second memory access instruction in response to the remaining address range at least partially overlapping with the second address range. With this method, address segment occupied by memory access instructions may be dynamically monitor, determination of the memory access control instructions being blocked may be refined, unnecessary waiting delays of processors may be reduced, and performance of the processor may be improved.

FIG. 1 illustrates an environment 100 where multiple embodiments are implemented according to embodiments of the disclosure. As illustrated in FIG. 1 , the environment 100 includes a computing device 102. The computing device 102 may be configure to execute program instructions.

The computing device 102 may include but not limited to a personal computer, a server computer, a handheld or laptop device, a mobile device (such as a mobile phone, a personal digital assistant (PDA), a media player, etc.), multi-processor systems, a consumer electronic product, a small computer, a large computer, a distributed computing environment including any of the above systems or devices, etc.

The computing device 102 includes a processor 104 and a memory 106. The processor 104 may be configure to execute various programs and control access to the memory 106.

The processor 104 may include a hardware processor, which may include but not limited to a hardware central processing unit (CPU), a field programmable gate array (FPGA), a composite programmable logic device (CPLD), an application specific integrated circuit (ASIC), a System on Chip (SoC) or any combination thereof.

As illustrated in FIG. 1 , the memory 106 has a program segment 108. The program segment 108 stores program instructions that may be executed by the processor 104, including a memory access instruction 110, a predetermined instruction 112, and another memory access instruction 114. For convenience of description, the memory access instruction 110 may also be referred to as a first memory access instruction, and the another memory access instruction 114 may also be referred to as a second memory access instruction. The program segment 108 illustrated in FIG. 1 including the memory access instruction 110, the predetermined instruction 112, and another memory access instruction 114 is an example. In other embodiments, the program segment 108 may include any number and any suitable type of instructions.

The memory access instruction 110 and another memory access instruction 114 are instructions that require to access the memory 106 when executed. In some embodiments, the memory access instruction 110 and another memory access instruction 114 may include the address ranges of the memory 106 to be accessed. In some embodiments, the memory access instruction 110 and another memory access instruction 114 may be read instructions and write instructions for the memory 106 or any other instructions for accessing the memory 106. The above examples are used to describe the present disclosure, but not to limit the present disclosure.

The predetermined instruction 112 is an instruction for monitoring the accessed address range in the memory 106. In some embodiments, the predetermined instruction 112 is an instruction obtained after adjusting the mfence instruction. When the predetermined instruction 112 is executed, a register or a cache may be scanned every clock cycle to obtain the remaining address space that is not yet accessed by the memory access instruction being executed. In some embodiments, the predetermined instruction 112 stops executing when the execution of the foregoing memory access instruction ends.

In a progress of executing the predetermined instruction 112, when the processor 104 obtains another memory access instruction 114, the second address range in another memory access instruction 114 compares with the obtained remaining address range. Whether to execute another memory access instruction 114 is determined by determining whether the two address ranges overlap. In response to the two address ranges overlapping, another memory access instruction 114 requires to be suspended.

In some embodiments, in the progress of executing the predetermined instruction 112, the stored remaining address range is updated every clock cycle. In response to the obtained updated remaining address range not overlapping with the second address range of the suspended memory access instruction 114, the suspended memory access instruction 114 is executed again. The above examples are used to describe the present disclosure, but not to limit the present disclosure.

With the method according to embodiments of the disclosure, the address segment occupied by the memory access instructions may be dynamically monitor, determination of the memory access control instructions being blocked may be refined, the unnecessary waiting delays of the processor may be reduced, and performance of the processor may be improved.

The above FIG. 1 illustrates the environment 100 where multiple embodiments are implemented according to embodiments of the disclosure. The following illustrates a schematic diagram a structure 200 for storing an address range in a storage device according to embodiments of the disclosure with reference to FIG. 2 .

As illustrated in FIG. 2 , a storage device 202 may store the address range to be accessed included in the obtained memory access instruction. The storage device 202 may be a cache or a register. For example, entries 204-1, 204-2, . . . , 204-N for a plurality of memory access instructions being executed are stored, and N is a positive integer. For convenience of description, these entries are collectively referred to as an entry 204. The entry 204 includes a flag bit part and an address part. The address part is configured to store the address range to be accessed by the memory access instruction. The flag bit is configured to identify whether the entry is valid.

When the memory access instruction is to be executed, the address range in the memory access instruction is stored in the entry 204. After the address range is stored in the entry 204, the flag bit of the entry is set to a first predetermined value, such as 1. After the memory access instruction executing the access to the address range completes, the flag bit is set to a second predetermined value, such as 0.

In some embodiments, when the memory access instruction is executed, the address part in the entry 204 corresponding to the memory access instruction is updated every clock cycle. The updated address part stores the address range that has not been accessed. When the predetermined instruction 112 is executed, the register or cache is periodically scanned to determine the remaining address range that has not yet been accessed.

In some embodiments, when the memory access instruction is executed, the address range to be accessed is stored in the entry 204. When the predetermined instruction 112 is detected and then executed, the address part of the entry 204 is updated to the remaining address range that has not yet been accessed, and then the register or cache is periodically scanned to determine the remaining address range that has not yet been accessed. The above examples are used to describe the present disclosure, but not to limit the present disclosure.

The above FIG. 2 illustrates the schematic diagram of the structure 200 for storing the address range in the storage device according to the embodiments of the disclosure. The following describes a flowchart of a method 300 for executing instructions according to some embodiments of the present disclosure with reference to FIG. 3 . The method 300 may be implemented by the computing device 102 in FIG. 1 or any other suitable devices.

At block 302, the computing device obtains the first memory access instruction for execution, and the first memory access instruction includes the first address range of the memory to be accessed. For example, the computing device 102 in FIG. 1 obtains the first memory access instruction when executing a program. The computing device 102 then executes the first memory access instruction.

In some embodiments, the computing device 102 receives the first memory access instruction. The first memory access instruction includes the address range to be accessed, which is also referred to as the first address range for convenience of description. When executing the first memory access instruction, the computing device 102 may store the first address range into the register or the cache. In an example, the first address range is stored in the register, and then a flag bit of the corresponding register is set to a predetermined value. In another example, the first address range is stored in the cache. After the first address range is stored in the cache, a corresponding a flag bit is set to identify that this address range is the address range to be accessed by the memory access instruction. The above examples are used to describe the present disclosure, but not to limit the present disclosure. In this way, the first address space may be used to quickly determine the remaining address range.

At block 304, the computing device determines whether the predetermined instruction for monitoring the accessed address range of the memory is detected. As illustrated in FIG. 1 , the computing device 102 detects the predetermined instruction 112 for monitoring the accessed address range in the memory.

In some embodiments, in response to no predetermined instruction 112 for monitoring the address range of the memory being detected, obtaining the subsequent instructions is continued, and then executing the subsequent obtained instructions is continued. Through the above method, other instructions may be executed quickly when the predetermined instruction 112 is not detected.

When the predetermined instruction 112 for monitoring the accessed address range in the memory is detected, at block 306, the computing device executes the predetermined instruction 112 to obtain the remaining address range not accessed by the first memory access instruction in the first address range. As illustrated in FIG. 1 , when the predetermined instruction 112 is detected during the execution of an instruction, for example, when a fence instruction for adjusting is detected, the computing device 102 may execute the predetermined instruction 112. At this time, the computing device 102 may obtain the remaining address range that has not been accessed by the memory access instruction prior to the predetermined instruction 112.

In some embodiments, the computing device 102 determines the accessed address range that has been accessed by the first memory instruction in response to detecting the predetermined instruction; and determines the remaining address interval based on the accessed address range. In this way, the address range that has not yet been accessed by the memory access instruction may be quickly and timely obtained.

In an example, when the first memory access instruction is executed, the first address range to be accessed by the first memory access instruction is written into the register or cache. When the predetermined instruction 112 is executed, the address range accessed by the first memory access instruction is detected, and the accessed address range is removed from the first address range stored in the register or cache to determine the remaining address range. Then the first address range in the register or cache is updated to the remaining address range that has not been accessed. Alternatively or additionally, in each clock cycle, the remaining address range that has not been accessed is updated based on the address range that has been accessed by the first memory access instruction.

In some examples, when the first memory access instruction is executed, the first address range is saved. When the memory access instruction is executed, the first address range is periodically updated to the remaining address range that has not been accessed every clock cycle. When the predetermined instruction 112 is executed, the register or cache is scanned to obtain the remaining address range.

In some embodiments, the computing device 102 obtains the remaining address range in each clock cycle. For example, when the predetermined instruction 112 is executed, the remaining address range is obtained at the end of each clock cycle. The above examples are used to describe the present disclosure, but not to limit the present disclosure. In this way, the accurate remaining address range may be obtained timely.

At block 308, the computing device compares the remaining address range with the second address range included in the second memory access instruction to be executed. At block 310, the computing device determines whether the remaining address range at least partially overlapping with the second address range.

At block 312, the computing device suspends the execution of the second memory access instruction in response to the remaining address range at least partially overlapping with the second address range. When the overlap exists, it indicates that the first memory access instruction and the second memory access instruction access the same address space. In order to ensure security and consistency of data, the second memory access instruction accessing to the memory requires to be suspended.

Combination with FIG. 4 , the process of determining overlap is described below. FIG. 4 illustrates a schematic diagram of an example 400 of an address range according to embodiments of the disclosure. The address range 402 in FIG. 4 is the remaining address range accessed by the first memory instruction. Another address range 404 is the second address range accessed by the second memory access instruction. As illustrated in FIG. 4 , the address ranges 402 and 404 are partially identical, which indicates that the two address ranges partially overlap. FIG. 4 is used to describe an example of overlap, and is not limit to the present disclosure.

Return to FIG. 3 to continue the description. In some embodiments, the computing device 102 periodically determines whether an overlapping range between the remaining address range and the second address range has been accessed by the first memory access instruction. For example, after obtaining the updated remaining address range every clock cycle, the computing device 102 determines whether the overlapping range between the remaining address range and the second address range has been accessed by the first memory access instruction. Executing the suspended second memory access instruction continues in response to the first memory access instruction accessing the overlapping range. Alternatively or additionally, when the second address range of the second memory access instruction also overlaps with the remaining address space of other memory access instructions executed prior to the predetermined instruction, executing the second memory access instruction is required to wait after the overlapping range that overlaps with the second address range is all accessed. In this way, the suspended instruction may be executed timely, which improves processing efficiency of the instructions.

In some embodiments, the computing device 102 executes the second memory access instruction in response to the remaining address range not overlapping with the second address range. In this way, it may be ensured that instructions that do not access overlapping address ranges are processed timely, which improves processing efficiency of the instructions and saves processing time of the instructions.

With the method according to embodiments of the disclosure, the address segment occupied by the memory access instructions may be dynamically monitor, determination of the memory access control instructions being blocked may be refined, the unnecessary waiting delays of the processor may be reduced, and the performance of the processor may be improved.
